3rd Assault Amphibian Battalion was originally activated 16 September 1942 at San Diego, California, as 3rd Amphibian Tractor (Amtrac) Battalion and assigned to the 3rd Marine Division. During December 1942 the battalion relocated from San Diego a short distance up the coast to Camp Pendleton. After training for a few months the battalion then deployed in February-March 1943 to Auckland, New Zealand in preparation for combat in the Pacific theater. During World War II, the battalion was primarily armed with Landing Vehicle Tracked (LVT), specifically the LVT-2 also known as "WATER BUFFALOS".
At the conclusion of World War II the battalion redeployed in March 1945 to Maui, territory of Hawaii and then relocated during February 1946 back to Camp Pendleton, California. It was Reactivated several months later on 1 May 1946.
3rd Amphibian Tractor Battalion was reactivated 1 April 1952 at Camp Pendleton, California, and assigned to Fleet Marine Force, Pacific. It was subsequently reassigned during October 1955 to the 1st Marine Division. Elements participated in the Cuban Missile Crisis, October–December 1962
During this period the battalion was still armed with LVTs - transitioning primarily to the LVT-5 in the late 1950s.
Description
The Battle of Iwo Jima (19 February – 26 March 1945), or Operation Detachment, was a major battle in which the United States Armed Forces fought for and captured the island of Iwo Jima from the Japanese Empire. The American invasion had the goal of capturing the entire island, including its three airfields (including South Field and Central Field), to provide a staging area for attacks on the Japanese main islands. This five-week battle comprised some of the fiercest and bloodiest fighting of the War in the Pacific of World War II.
After the heavy losses incurred in the battle, the strategic value of the island became controversial. It was useless to the U.S. Army as a staging base and useless to the U.S. Navy as a fleet base. However, Navy SEABEES rebuilt the landing strips, which were used as emergency landing strips for USAAF B-29s.
The Imperial Japanese Army positions on the island were heavily fortified, with a dense network of bunkers, hidden artillery positions, and 18 km (11 mi) of underground tunnels. The Americans on the ground were supported by extensive naval artillery and complete air supremacy over Iwo Jima from the beginning of the battle by U.S. Navy and Marine Corps aviators.
Iwo Jima was the only battle by the U.S. Marine Corps in which the Japanese combat deaths were thrice those of the Americans throughout the battle. Of the 22,000 Japanese soldiers on Iwo Jima at the beginning of the battle, only 216 were taken prisoner, some of whom were captured because they had been knocked unconscious or otherwise disabled. The majority of the remainder were killed in action, although it has been estimated that as many as 3,000 continued to resist within the various cave systems for many days afterwards, eventually succumbing to their injuries or surrendering weeks later.
Despite the bloody fighting and severe casualties on both sides, the Japanese defeat was assured from the start. Overwhelming American superiority in arms and numbers as well as complete control of air power — coupled with the impossibility of Japanese retreat or reinforcement — permitted no plausible circumstance in which the Americans could have lost the battle.
The battle was immortalized by Joe Rosenthal's photograph of the raising of the U.S. flag on top of the 166 m (545 ft) Mount Suribachi by five U.S. Marines and one U.S. Navy battlefield Hospital Corpsman. The photograph records the second flag-raising on the mountain, both of which took place on the fifth day of the 35-day battle. Rosenthal's photograph promptly became an indelible icon — of that battle, of that war in the Pacific, and of the Marine Corps itself — and has been widely reproduced.
